The Cellarius Collectionwas started from a scan from one of Andreas Cellarius drawings of the Copernican System (Amsterdam, 1660):
"Andreas Cellarius, the Celestial Atlas of Harmony" (The British Library, 2003).

* The Zodiacs are variations of the logo of my Brussels astrology school, "Aire du Temps-Espace Astro", originally drawn by Andre Vander Linden.

* The planets backgrounds where worked from a scan of my book, the "Ephemerides previsionnelles 1960-2020".
